This dude messed up by the numbers, killed a man, and wrecked his life and his family's life, in addition to those of his victim and his victim's family, all because he was stupid and believed a lot of the sort of BS self-defense advice you pick up from well-meaning ignorant morons in gun stores and on the internet.

Folks, self defense with a firearm is no joke. This is life and death stuff right here; it literally does not get more serious than that. With great power comes great accountability..
